The host of the railing.

Namespace: Autodesk.Revit.DB.Architecture
Assembly: RevitAPI (in RevitAPI.dll) Version: 22.0.0.0 (22.1.0.0)
Since: 2013

Syntax

C#
`public ElementId HostId { get; set; }`

Visual Basic
`Public Property HostId As ElementId Get Set`

Visual C++
`public: property ElementId^ HostId { ElementId^ get (); void set (ElementId^ value); }`

Remarks

If the host will be a Stairs in MultistoryStairs element, use [M:Autodesk.Revit.DB.Architecture.Railing.SetMultistoryStairsPlacementLevels(System.Collections.Generic.ISet`1{Autodesk.Revit.DB.ElementId})] to set the base levels of the stairs where the railing should be placed.

If %hostId% is the id of a Stairs Component (Run or Landing), it means that the Railing will be hosted by the Stairs element but railing adjustment to the stairs will start from the Component. If a stairs id is set as a host, the lowest stairs component below or above the railing sketch will be chosen as the host instead.
